2008 Nightly Reportsand Remote Observations By ~ PJ Sallave - Goldfinger
Observing Protocol • To assure the Highest Quality of scientific output possible for the PI’s . • The Observing Assistant has full responsibility for night-time operation of the Array/Observatory, related observing equipment. • To continually evaluate the Array system status, including environmental control functions, and schedules of the targets to be observed. • Insure safe use of the instruments and systems during remote observations - We are watching !!!
Observing Statistics 2008Based on nightly observing reports • 269 Observing Sessions attempted • 115 had multiple instruments running • 77 nights lost mainly due to weather • Highest reported seeing values in August • Only three full nights noted being lost to technical issues !! • The most prevalent technical issues were - Carts getting stuck on rails - S2 telescope computer rebooting itself - Bandwidth due to remote observation - Telescope domes and enclosures
Remote Observing Protocol The current CHARA protocol is that if Remote Observation time is allocated … • The Remote Observer must first be trained and fluent in Array operations. • We insist and will check that Astronomers have observational experience and once again are acquainted with the Software and Observing manuals. • Also required for first time observers is a trip and visit for an accompanying observing run at the CHARA Array to learn observing techniques firsthand. • Learning over Skype or running things with just a few nights practice is not sufficient and will not qualify for remote observations. • To insure safe use of the instrument . • CRUCIAL TOOLS * Take Notes* The Weather Gui* Sockman* Patience !!!
Remote Facilities • All with hard copies of CHARA procedure documents at observing stations !!! • Atlanta • Sydney • Grasse
Modes of Operation • Primary observing: • Just like normal observing • Use Primary GW & OPLE • Secondary observing: • We try to stay out of the way :-) • Use Secondary GW & OPLE • Slide credit Ellyn Baines 2004
Remote Observation Tips • Carts, Beams, Telescopes • Weather GUI • Sockman • Use CHARA documents - Software Overview - Remote Observing Guide
Array Initialization 2008- Reminder - • Over 4000 pieces of Hardware, Software and Equipment need to be started and shutdown each observing session with six beams. • Does not include technical problems !!! `
Alternative Observing Scenarios • The Q is still available for use • Inquire about substitute observing modes • Choose Targets that are in different parts of the sky • Have targets ready for capricious weather conditions Ex: Bad seeing,wind, a bright source would be better • Time Saving - Pre Check for background stars in the star fields

2008 Observing Memoirs confessions…. • Headline Remote Observations from Sydney - - Pavo Crashes TCS on All 6 Domes - • Gail breaks filter wheel - • Ming and Ajay candle light observing (Observations done all night with back lights on in lab)
